What is an Interim Storage Facility (ISF)?

19

♦It is estimated that generated soil from decontamination will be approx. 16 ~22 mil. m3 after the volume reduction incineration (Ref: approximately 13~18 times as much as the volume of Tokyo Dome (1.24 mil. m3)※In considering the plan for the Interim Storage Facility, storage of products whose volume is difficult to estimate at this moment is also taken into account.

♦In Fukushima Prefecture, large quantities of removed soil and waste have been generated from decontamination activities.

♦Currently, it is difficult to clarify methods of final disposal of such soil and waste.

♦Until final disposal becomes available, it is necessary to establish an Interim Storage Facility (ISF) in order to manage and store soil and waste safely .

The following materials generated in Fukushima Prefecture will be stored in the ISF. 1. Soil and waste (such as fallen leaves and

branches) generated from decontamination activities, which have been stored at the Temporary Storage Sites.

2. Incineration ash with radioactive concentration more than 100,000 Bq/kg.

(Review) Technology Development Strategy for Volume Reduction & Recycling of the Removed Soil

Towards the final disposal of the removed soil outside Fukushima Pref., MOE will promote recycling of the soil after volume reduction technology as much as possible, which consequently would lead to reduce the volume of soil for the final disposalAfter clarifying the objectives and priority of technology development and volume reduction & recycling, basic technology development is planned to be completed within 10 years, then move onto a phase of treatment On the premise of securing safety, MOE will try to realize the recycling in the possible field, building public understandings for the safetyBased on technology development and prospect of recycling in the future, MOE would propose some options for structure and necessary dimension of the final disposal

【Basic Concept】The contaminated soil should be used mainly for public projects as the controlled materials (with radioactivity level below 8,000Bq/kg in principle and set according to purpose) after necessary treatment, e.g. removal of debris, classification treatment, and be managed by the public authorities.

【Limited Use】The use will be limited such as basic structure material of banking for coastal levee, seaside protection forest, or embankment materials for roads, which assumed not to be changed the form artificially for a long time period. It will be also used as covering soil for waste disposal site.

【Management by the public authorities 】The criteria should be formulated based on the Act on Special Measures and be managed by MOE and public entities (municipalities, etc.)

To be specific, in order to confine additional exposure dose as below 1mSv/y at the time of construction and below 0.01mSv/y at the time of service, radioactive level of recycled materials should be limited, covering soil should be installed, scatter and leakage should be prevented, ground form change should be observed, and the data should be recorded.

【Procedure of recycling】To realize the recycling of contaminated soil, demonstration and model projects based on concepts above should be implemented keeping the safety against radiation, studying specific verification of management method, and building stakeholders’ understandings .

Public CommunicationProvision of basic and comprehensive information■Web http://josen.env.go.jp/en/ ■Call centers in Fukushima and in Tokyo

Exhibition at Tokyo about “Steps for Restoration of Fukushima”

■Providing interactive communications with people and municipalitiesEnvironmental Regeneration Plaza (Information hub run by MOE and Fukushima Pref.)

• Interactive exhibition and workshops • Dispatch of experts to municipalities, communities, schools, etc.

• Distributed at meetings, workshops, city offices, banks, and supermarkets in Fukushima, and also available on the Web

■Providing easy-to-understand information with detailed data on decontamination and radiation

Pamphlets, comic books, and videos

Collaboration with media

• ”Thanks Helmet”, a campaign to motivate the decontamination workers and improve relationships between the residents and the workers

■Providing information that helps people understand remediation and the state of the region after remediation, in collaboration with media in Fukushima• Newspaper ads and TV/radio programs

Development of national public understanding

PR of rice harvested from decontaminated paddy fields

■Widely disseminate information to the public of remediation and the state of the region after remediation so that they can correctly understand the current status of Fukushima and its products

Current PR Activities by MOEJ Ministry of the Environment, Japan (MOEJ) released an English booklet in August. English web-site, “Environmental Remediation” was also renewed and two TV shows are now available on MOE’s web site.

Channel Japan/CNBC ASIA: CNBC broadcasted 15-minitues program 4times in a row.Each program showed you the key persons in Fukushima how hard they work to fight against misconceptions and to revitalize Fukushima. Each content is as follows;

#1 The story of Mr. McMichael, who tries to help widely communicate correct information on Fukushima to international communities

#2 The story of two young people who are eager to revitalize their hometown, Fukushima

#3 The story of small factories that tackle on the development of robots for decommission. #4 The story of Dr. Hayano, who teaches what is radiation from academic point of views.

“Fukushima Diaries” by Discovery Channel: In this 30-minitues show, three famous bloggers from overseas visited different destinations in Fukushima Pref. with their own interests. They showed the viewers what is really going on in Fukushimahttp://josen.env.go.jp/en/movie_publication/cooperation_index.html
